netstat -a -> outputs:

edit: added the column headers:

Code:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
udp        0      0 <domain redacted>.:47949 50.28.8.224:ntp         ESTABLISHED
udp        0      0 <domain redacted>.:52313 mail.freerip.com:ntp    ESTABLISHED
udp        0      0 <domain redacted>.:52074 conquest.kjsl.com:ntp   ESTABLISHED
udp        0      0 <domain redacted>.:52148 barricade.rack911.c:ntp ESTABLISHED



What are these, and should I be concerned?

It seems to be your NTP (time synchronization) client, connecting to some NTP servers -- probably NTP pool servers, which are run by volunteers of varying reputability, but serve good time.
